Application September 11, 1935,

2 Claims.

This invention relates to a valve and while it is designed primarily for use in connection with wine pumps, it is to be understood that the same may be utilized for other purposes where it is desired to use a valve which can be easily cleaned and which will operate efiiciently to open or shut the ports leading thereto.

It is a further object of the invention to provide the valve with automatically adjustable cut off elements so shaped as to fit tightly against the surfaces cooperating therewith and to automatically compensate for wear.

A still further object is to provide a valve especially adapted for use in controlling the flow of liquids containing more or less solid sub stances (as, for example, wines) which tend to clog any internal protrusions and to render valves of ordinary construction inefiicient.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is a plan view of a four-way valve having the present improvements combined therewith.

Figure 2 is a section on line 2-2 Figure 1.

Figure 3 is a section on line Referring to the figures reference, I designates a valve casing which, in the present instance, is provided with four equally spaced radial ports indicated at 2, al-

though it is to be understood that the number of these ports can be reduced if desired.

The valve casing is provided with heads 3 and 4, the head 3 being formed with a central socket 5 while the head 4 has a central opening 5 which can be surrounded by a packing gland 1 or the like.

Mounted for rotation within the socket 5 is a trunnion 8 having a recess 9 extending thereinto and this trunnion is located at one end of an arm I0 located at one end of a bar II which extends from head 3 to head 4. Another arm I2 is provided at the other end of this bar II and has a stem I3 which extends through the opening 6 and is provided at its outer end with an operat- Serial No. 40,138

ing handle manner.

Rotatable within the opening 6 and upon the stem I3 is a tubular stem I5 to the outer end of which is connected a handle l6 while the inner end thereof extends partly across the end of arm I2 and is made integral with an arm I'I extending from one end of a bar I8. This bar is similar to the bar II and extends from head 4 to head 3. That end of the bar I8 remote from arm I'Ihas an arm I9 carrying a trunnion I9 which is mounted for rotation in the socket 5 in the trunnion 8.

Each of the. bars II and I8 is seated in a channel formed by parallel ribs 20 extending from an arcuate guard plate 2I the outer surface of which corresponds with the curvature of the cylindrical inner surface 22 of valve casing I. Springs 23 are interposed between these plates 2| and the bars to which they are joined and these springs, which preferably are bowed as shown in Figure 2, operate to hold the arcuate outer faces of the valve plates 2| pressed firmly against the inner surface 22 of the valve casing. The ends of the channels formed by ribs 20 are closed by the heads 3 and 4 and the ends of the bars II and I8 bear against these heads. Therefore pulp and other foreign substances are kept out of the spaces in the channels and will not interfere with the relative movement of the parts. I

The longitudinal edges of the. plates 2I can be beveled as shown at 24 and to these edges can be secured scraping or cutting blades 24 of stainless steel or other hard non-corrosive material which act to out through stems, skins or other solid substances with which they may come into contact at the ports, thereby preventing the valve from becoming clogged. These blades can be secured to the valve members 2I in any manner desired.

It will be apparent that by providing two valve plates 2I with the respective stems I3 and I5, the said plates can be operated independently or simultaneously for the purpose of controlling the flow of fluid through one or more of the ports. At all times these blades are maintained in intimate contact with the inner surface 22 of casing I so that leakage will be prevented. At the same time the cutting blades provided on the plates will enable said plates to be operated in spite of any accumulations of solid substances which might be located at the ports and in the paths of the plates.

By removing one or both of the heads 3 and I4 joined thereto in any suitable 4 the internal mechanism of the valve can be removed easily for the purpose of cleaning or repairing them, it being understood that these heads are held detachably in place by any suitable means provided for that purpose such as bolts 25 seated in projecting ears 26 on the heads and casing.

'What is claimed is:

1. A valve of the class described including a casing having ports opposed heads, and 9. cylindrical inner surface, bars mounted to move Within a circle contact at its ends With carried by and said plates hearing at their ends against the heads and each having an arcuate outer surface corresponding in curvature wit the cylindrical 1nner surface of the casing, there-'being a' channel in each plate closed at the ends by theheads and between its ends by the bar, means interposed between the bar and platetfor maintaining said outer surface of the plate in intimate :contact with the inner surface of the casing, and separate means for independently moving the respective plates in the same direction or toward or from each other along the cylindrical inner the heads, valve plates in the casing and having wiping slidable on the respective bar s,

surface to open or close predetermined ports,

either of said plates being movable against the close the space between channel and closing it between its ends, a spring interposed between the bar and plate for maintaining said plate in yielding contact with the cylindrical surface of the casing and separate means for moving the respective plates in the same direction or toward or from each other along said cylindrical surface of the casing to open or close selected ports and the space between the plates.
